RADIATOR-FITTING.

Apneanon'aiea october so, 1912.

To (zr/ZZ whom t may] concern.'

Be it known that I, F RANK E. BUTTS, a citizen of the United States, and a resident of' the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful improvements in Radiator-Fittings, of which the following is a specification.

My invention relates to radiator fittings and the object of this improvement is to provide a fitting having a passage for live steam and a return passage for condensed steam entering and leaving the radiator through the same opening.

A further object is to provide a device of this character which will be simple in its construction and efficient in its operation.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which,

Figure 1 is an end elevation of a radiator equipped with a fitting made in accordance with my invention, Fig. 2 is a vertical section of the same taken on lline 2 2 in Fig. 1, Fig. 3 is a longitudinal section of the fitting, in perspective, showing the arrangement of the passages through such fitting, and Fig. l shows the method of connecting the fitting with pieces of pipes to form a water heater and the like.

The preferred form of construction, as illustrated in the drawings, comprises a substantially Y-shaped fitting 5 having a passage 6 extending through the stem portion 7 and one branch portion 8 of the fitting and is adapted for the return of condensed steam. Said fitting is provided with a second passage 9 extending through the other branch portion 10 of the fitting and sepa rated from said passage 6 by means of ay transverse partition 11. Such partition 11 is provided with a threaded opening in axial alinement with the stem 7 of the fitting. In the opening in the partition 11 is threaded a pipe 1Q having an upturned elbow portion 13. The passage 9 is provided for the passage of live steam. When the fitting 5 is applied to a radiator. as illustrated in Fi gs. 1 and 2. the pipe 12 has its elbow directed upwardly opposite the opening in the censpeciacatioa of Leiters raient.

tral column of the first section vof the radiator so that steam passing through passage 9 will be directed upwardly through the elbow 13 and up through the columns of the first section of the radiator. Upon the steam reaching the top of the radiator it passes through the radiator nipple 14 between the first and second sections, a part goes downwardly through the second section and the balance going through the second radiator nipple 141 into the succeeding sections of the radiator and passes back through the radiator nipples 15 in the lower part of the radiator, through the passage 6 and is returned to the steam generating plant, not shown, in the usual manner.

The fitting may be used as a connection for a water heater of simple construction, as clearly shown in Fig. t. In this device the fitting 5 is provided with an open pipe 15 threaded in the partition 11 and eX- tended through the central portion of the stem 7. A second and larger pipe 16 is con nected to the stem portion 7 of the fitting by means of a collar 17 and its other end closed by means of an ordinary fitting cap 18. number of similar uses will suggest themselves to one familiar with the art to which this fitting belongs.

For use in radiators, the elbow 13 directs the live steam upwardly t0 the top of the radiator where it is divided and returned through all of the columns of the radiator descending and collected again and passed through the stem portion 7 and out through the branch 8 and returned to the source of steam supply. With this arrangement it will be seen that'the live steam at no time is mixed with the condensed steam thus insuring the best circulation and effective ness of the steam.

While I have illustrated and described the preferred form ef construction for carrying my invention into effect. this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth. but desire to avail myself of such variati/ris and modifications as come within the scope of the appended claim.

Having described my invention what l claim as new and desire to secure by Letters Patent is:

A radiator fitting comprising an integral stem and a Ipair` of parallel branch portions7 a transverse partition extending partially across said tting and dividing one of said branchY portions from the other and the stem, there being an opening in said partition in axialalinement With said stein and of less diameter than the opening in said stem, the Walls of the opening in said par-Y tition being threaded and said stem being Copies of this patent may be obtained for ve cents each, by addressing the Commissioner of Patents, Washington, D.
